Abstract: Operation method for a variable speed wind turbine which comprises control methods for blade pitch in cases of extreme gusts of wind, characterised by the fact that it is comprised of the following steps: a) detection of the presence of an extreme gust of wind; b) performance of a sudden increase in pitch within the range of 6 to 14 degrees at the maximum speed permitted by the wind turbine blade pitch control mechanisms. The method also includes an additional step; c) vary the generator speed to avoid an increased acceleration of the generator which could make a subsequent step b) necessary.

Abstract: A floating foundation for wind turbines is disclosed, where the foundation essentially comprises at least three submerged buoyancy bodies connected to the lower end of the tower of the wind turbine at a common node member situated well above the surface of the sea. The buoyancy bodies are connected to the node member by means of relatively thin leg sections, whereby wave load on the foundation is reduced. By applying the foundation according to the present invention, stress concentrations and torques in the node member are reduced, whereby it becomes possible to apply a relatively lightweight and hence cheap node member. The overall weight of the construction is thereby reduced and hence the volume of the buoyancy bodies necessary to counteract the overall weight of the construction.
